I like beer, bars / pubs and crazy, curious things.
Szimpla Kert is a ruin bar that has all the above. There are a number of things hanging on the wall and a chessboard with several buttons that make crazy things anytime you press them.
You can rent shishas with different recipes and upstairs there's something to eat. There's some sort of pizza or sandwich that is good to stuff (it worth if you are planning to have some Palinkas).
Definitely, it worth the visit!!!
